LiteGraph lifecycle coverage
Workflow flattening coverage
Copy-paste coverage
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: ⚪ Minimal · up to This PR adds behavior-level regression tests without changing production behavior. The remaining risks are limited to test determinism, cleanup isolation, and assertion strength, so no actionable merge-blocking risk remains beyond normal test-quality follow-up. Possibly related PRs

Load a deterministic minimal workflow.
This test depends on the fixture's implicit default workflow and its first node. A change to that workflow can fail the test before it exercises copy/paste. Load a checked-in minimal workflow in a test-scoped beforeEach, then target a known node.
As per path instructions, “Load the smallest workflow the test needs,” not the full default graph. (raw.githubusercontent.com)

Reset the canvas view after the test.
node.centerOnNode() changes the canvas viewport. Add a file-level test.afterEach that calls comfyPage.canvasOps.resetView().
As per path instructions, tests that manipulate canvas view should call resetView() in afterEach. (raw.githubusercontent.com)

Assert that the graph gains exactly one node.
The current assertion only checks nodes with nodeType. It can pass if paste adds the expected node plus extra nodes of other types. Record the total graph count before paste and assert that it increases by one.
Proposed assertion
const originalNodes = await comfyPage.nodeOps.getNodeRefsByType(nodeType)
const originalIds = new Set(originalNodes.map(({ id }) => id))
+const originalGraphNodeCount =
+ await comfyPage.nodeOps.getGraphNodesCount()

Avoid coupling this regression test to traversal order.
The exact array assertion requires collectSubgraphDefinitions to return def-A before def-B. The stated behavior is that both cyclic definitions are collected exactly once. Unless traversal order is part of the function contract, assert the result length and the set of IDs instead.
As per path instructions, the required test-quality guidance says to avoid fragile ordering assumptions.
Proposed assertion
- expect(collectSubgraphDefinitions([defA]).map(({ id }) => id)).toEqual([
- 'def-A',
- 'def-B'
- ])
+ const ids = collectSubgraphDefinitions([defA]).map(({ id }) => id)
+ expect(ids).toHaveLength(2)

## Summary Extract behavior-focused regression coverage from Comfy-Org#14246 that passes independently against `main`. This consolidates the former stacked PRs Comfy-Org#15323 and Comfy-Org#15325. ## Changes - Add Playwright coverage for renderer transitions, subgraph layout and reroutes, node replacement, pinned-node copy/paste, widget persistence, app-mode validation, and legacy drag performance. - Add unit coverage for graph removal and disconnection lifecycle, dynamic-input connections, cyclic subgraph definitions, semantic widget errors, and mixed drag selections. - Assert observable behavior and public contracts without depending on ECS stores or private migration state. ## Review Focus All coverage is independently mergeable into `main`; tests that require the ECS migration implementation remain in Comfy-Org#14246. --------- Co-authored-by: Amp <amp@ampcode.com> Co-authored-by: coderabbitai[bot] <136622811+coderabbitai[bot]@users.noreply.github.com> Co-authored-by: github-actions <github-actions@github.com>
